Bat's Day is lots of fun and I highly recommend it to anybody who can go. There are few things like being at Disneyland when there are enough people in black running around to make everybody else think there is a movie being filmed or something.

anyway, Bats Day is best in the evening, when the sun goes down. Everyone meets at the Haunted Mansion around 8:00pm. And last year, it was quite a big crowd. Disney has their photographers situated around, so there's plenty of opportunity for photos. And the 'group' shot in front of the Haunted Mansion is much better than any school or renunion picture.

I can see this event getting so popular that someday they will have to spread it out into 2 or 3 days!
